The Ohio State University football stadium was last repaired extensively in 1948, leaving unsightly dark, irregular patches. Numerous stains, spalling concrete, and exposed steel reinforcement called for further repair of the concrete facing. Most of the precast cornices and all the precast window grilles were in an advanced state of deterioration due to freeze-thaw damage with many pieces already having fallen to the ground. Cored samples of the concrete surface in several locations indicated a depth of carbonation in the concrete ranging from one-eighth to one and one-half inches. Orange streaks also stained the exterior of the stadium concrete.
